It's 2 weeks from February 16 to March 1st so if you truly were 5 weeks pregnant, it's not the "friend's" baby BUT Doctors have been wrong about due dates, conception dates.
The only way to know is to have DNA testing when the baby is born.
Is your boyfriend aware that this may not be his chld?
Ok sorry I got the dates all wrong I went to the doctor on April 2 witch it was a Monday n they told me I was 5 weeks pregnant but I had sex with my bf in the past then on February 16 I had sex with a friend later on that month I had sex with my bf but I believe I was already pregnant ?? Tomorow June 18 I will b 16 weeks pregnant n I had been going to the doctors since I found out that I was preggo n they haven't change my due date ...
